From fd5d7947f614d837cb3b08e132a025c4e1536d37 Mon Sep 17 00:00:00 2001 From: lat9nq <22451773+lat9nq@users.noreply.github.com> Date: Tue, 20 Jun 2023 15:49:47 -0400 Subject: time_zone_manager: Stop on comma This is a deviation from the reference time zone implementation. The actual code will set a pointer to the time zone name here, but for us we have a limited number of characters to work with, and the name of the time zone here could be larger than 8 characters. We can make the assumption that time zone names greater than five characters in length include a comma that denotes more data. Nintendo just truncates that data for the name, so we can do the same. time_zone_manager: Check for length of array Just to be double sure that we never break past the array length, directly compare against it. --- src/core/hle/service/time/time_zone_manager.cpp | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/core/hle/service/time/time_zone_manager.cpp b/src/core/hle/service/time/time_zone_manager.cpp index 63aacd19f..43d0a19b8 100644 --- a/src/core/hle/service/time/time_zone_manager.cpp +++ b/src/core/hle/service/time/time_zone_manager.cpp @@ -911,7 +911,9 @@ static Result ToCalendarTimeInternal(const TimeZoneRule& rules, s64 time, calendar_additional_info.is_dst = rules.ttis[tti_index].is_dst; const char* time_zone{&rules.chars[rules.ttis[tti_index].abbreviation_list_index]}; - for (int index{}; time_zone[index] != '\0'; ++index) { + for (u32 index{}; time_zone[index] != '\0' && time_zone[index] != ',' && + index < calendar_additional_info.timezone_name.size() - 1; + ++index) { calendar_additional_info.timezone_name[index] = time_zone[index]; } return ResultSuccess; -- cgit v1.2.3
